GATE LATCH.

Application filcclJanuary 29, 1924:. Serial No. 689,343.

To all whom it may ooncem:

Be it known that we, THOMAS O. THovsoN, Emma BRAY, CARL S. Brennan, andOLIVER BRAGER, citizens of the United States, residing at Hanlontown, inthe county of lVorth, State of Iowa, have invented certain new anduseful Improvements in Gate Latches; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to gates, and particularly to gates used inconnection with hog pens and houses.

One object of the invention is to provide a device which will releasablyhold the door of a hog house in closed position, against being movedinto open position by wind.

Another object is to provide means by means of which, when the door,which door closes by gravity, reaches its full closed position, it willnot have a tendency to swing back and forth, but will be properly heldin closed position.

Another object is to provide a device of this character which willpermit the door to swing open to its full position without interferencetherewith, but which will act upon the door, when said door is relievedfrom the opening pressure to more quickly restore the door to its fullclosed position.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is an elevation of a door, and its enclosing frame, equippedwith the present invention.

Figure 2 is ahorizontal sectional View on the line 2-2 of Figure 1, thepartially open position being shown in dotted lines.

Figure 3 is a vertical sectional view on the line 3-3 of Figure 1, oneof the closing arms being in elevated position, and the door partlyopen.

Referring particularly to the accompanying drawing, there is shown adoor frame including the top and bottom rails and 11, and the verticalside stiles 12 and 13, connected thereto. Secured to the stile 13, andextending between the rails 10 and 11, is an inverted right triangularmember 14:, and carried by the upper end of this member is thestationary member 15 of the upper hinge, while the stationary memher to,of the lower hinge is carried by the lower end of said member, thislatter nieinber 16 being also secured to the stile.

' conforming to the outline of the rails 10 and 11 and stile 12, whilethe fourth side is inclined in conformity to the edge of the member 14.By this construction, the door. which carries the other members 18 and19. of the upper and lower hinges, respective ly, is adapted togravitate to closed position withln the frame, when opened and released.The door, when swinging into closed position, will vibrate back andforth. before finally settling into position within the door frame, andit is with this difficulty in new that the present device is provided.It will be noted that the upper member of the hinge carried by the doorextends longitudinally on the upper edge of the door. for a suitabledistance from the member 14.

fiecured to the lower face of the upper rail 10, and extendingtransversely thereof. is a strip 20. and pivotally supported on each endof this strip, and depending against the face of the door, is an angulararm 22, the free end of which is directed toward the hinged edge of thedoor. These arms 22 are preferably of heavy metal. so that they willgravitate into depending posi tions, against the faces of the door, andalso to act upon the door to move the same into full closed position,within the door frame. The free end of each arm 22 is adapted to beelevated when the door is swung into open position, and to ride on thedoor carried portion. of the upper hinge, which hinge portion serves asa wear plate to protect the door. 7

The positions of the hinges, of the door, causes the door to gravitateinto closed position, when released, but due to the fact that the doorwill have a tendency to vibrate when in its nearly closed position. theweighted arms 22 are provided to overcome thls and cause the door toquickly settle into full closed position. Furthermore, the arms are ofsufficient weight to resist the opening movement of the door underpressure of wind. The door may, however, be easily pushed into openposition by the hogs, when passing into and out of the hog house. Thusthe door will be held against accidental opening movement, so thatdrafts, within the house, will be prevented.

lVhat is claimed is:

The combination with a doorway and a gravity closing door mountedtherein for swinging movement in opposite directions, of a transversemember secured to the upper portion of the frame 01 the doorwaytransversely thereof and above the said door, said member having bearingmeans on its opposite ends disposed beyond the side faces of the door,and an L-shaped arm pivotally suspended on each end of the transversemember and depending against the side face or the door, said arm beingarranged to be swung upwardly by the door In testimony whereof, we afiiXour signatures, in the presence of two witnesses.
